Given Focus $(6,0)$ and Directrix $x=-6$
Since the Focus is on the x-axis $\rightarrow$ this is the axis of the parabola.
The Directrix is to the left of the y-axis, while the Focus is on the right.
Therefore, this is of the type $y^2=4ax$ where $a = 6$
Therefore the equation of the parabola is $y = 4 \times 6 \ x = 24x$
